父类
package org.hanqi.array;
public class Son
extends Father {
public Son()
{
super("儿子"
);
System.out.println("子类的构造方法"
);
}
public void work()
{
super.work();
System.out.println("我边上班边练歌"
);
}
}
子类
package org.hanqi.array;
public class TestJiCheng {
public static void main(String[] args) {
Father f=
new Father("父亲"
);
//f.setName("父亲");
f.setAge(50
);
System.out.println("名字是："+f.getName()+" 年龄是："+
f.getAge());
f.work();
System.out.println();
Son s=
new Son();
//s.setName("儿子");
s.setAge(20
);
System.out.println("名字是："+s.getName()+" 年龄是："+
s.getAge());
s.work();
}
}
测试类
总结：构造子类时需要先构造父类，当需要调用父类的被覆盖的成员时，可以用super关键字调用
